Al Green will croon at Obama fundraiser

2/16/12 12:58 PM EST

Legendary soul singer Al Green will perform at a fundraiser tonight with President Obama in San Francisco, a campaign official confirms to POLITICO.

Green will sing at an intimate dinner for about 70 supporters in a private residence in the city, with tickets costing $35,800.

Green's 40-year old song "Let's Stay Together" rocketed back to the top of the sales charts in late January, after video surfaced of Obama singing a few bars at a Harlem fundraiser — a video that became a viral sensation.

Green was also in attendance at the Harlem fundraiser — and he told TMZ in January that the president "nailed' the cover of his song.
